The length field 425 may refer to the length of the payload 430. Here, the variable range of the length field 425 may be 6 to 37 octets. The RFU field 422, the TxAdd field 423, the RxAdd field 424, and the RFU field 426 may be further included.

PDU types of the PDU type field 421 included in the header 420 of the advertisement channel PDU 416 may be used in specific events as described below.

'ADV_IND' is connectable and can be used for an advertisement event that does not specify a receiving device, 'ADV_DIRECT_IND' is connectable, the receiving device can be used for a specific advertisement event, 'ADV_NONCONN_IND' is not connectable, &Quot; ADV_SCAN_IND " can be used for an advertisement event that is scanable and does not specify a receiving device.

These PDU types may be transmitted through the link layer in an advertising state.

Here, the PDU type of each of ADV_IND, ADV_NONCONN_IND, and ADV_SCAN_IND may indicate that the broadcast is not specifying the receiving apparatus. Thus, it can be received by any device located in the transmission range of the transmission device.

The ADV_IND type can also be used to establish a connection with at least one receiving device. However, the ADV_NONCONN_IND type can be used to perform non-connectable or one-way communication with at least one receiving apparatus. On the other hand, the ADV_SCAN_IND type can be used to perform a SCAN_REQ-capable communication in at least one receiving apparatus.

Here, the payload 430 of both ADV_IND, ADV_NONCONN_IND, and ADV_SCAN_IND may be the same. Payload 430 AdvA field 432 and AdvData field 434. AdvA field 432 may include an advertiser's public or random address.

AdvData field 434 may include advertising data at the advertiser's host. In one example, if the short-range wireless communication device 300 is an advertiser, the advertisement data may be referred to as an advertisement message, and the advertisement message may be defined by a format of the advertisement message that can be transmitted in a near field wireless communication protocol. Here, the advertisement message format may require a minimum amount of data to conserve low energy, or may include as many advertisement messages as possible in each packet. In another embodiment, the advertising message format may allow variable length or variable size of the advertising message depending on the purpose of the advertising message or the type of broadcasting message. For example, some advertising messages may be short between 2 or 8 bits, and may have as large a size as needed in a communication protocol if many octets are needed.

This advertisement message may be formatted to be included in the AdvData field 434 of the payload 430 of the PDU 416 of the ad channel packet 410. In one example, AdvData field 434, as shown, may include advertising messages 0 through 31 octets. Accordingly, the advertisement message in the AdvData field 434 may include the data in the range, and data exceeding the range may be separately transmitted to the other advertisement channel packet 410.

In addition, a plurality of advertisement messages may be included in the AdvData field 434 of one advertisement channel packet 410. For example, the advertisement message 1, the advertisement message 2, ..., the advertisement message N may be included in the AdvData field 434 of one advertisement channel packet 410.

On the other hand, the ADV_DIRECT_IND type may indicate that the receiving apparatus is a specific broadcast. Here, the payload 430 of ADV_DIRECT_IND may be composed of an AdvA field and an InitA field. The AdvA field may include the advertiser's public or random address and may include the public or random address of the InitA field initiator.

The PDU types of the advertisement channel PDU 416 may further include the following types.

'SCAN_REQ' may be transmitted in the link layer of the scanning state and received in the link layer of the advertisement state, 'SCAN_RSP' may be transmitted in the link layer of the advertisement state and received at the link layer of the scanning state, and 'CONNECT_REQ' May be sent at the link layer in the initial state and received at the link layer in the advertisement state.

According to an embodiment of the present invention, the short range wireless communication apparatus 300 or the mobile terminal apparatus 100 installed in a specific location operates in the advertisement state as described with reference to FIGS. 10 and 11, Identification information may be included in the AdvData field 434 of the advertisement channel packet 410 and broadcasted.

The PDU type of the advertisement channel packet 410 broadcasted from the short range wireless communication apparatus 300 or the mobile terminal apparatus 100 may be any one of ADV_IND, ADV_DIRECT_IND, ADV_NONCONN_IND, and ADV_SCAN_IND . ≪ / RTI >

For example, when the PDU type of the advertisement channel packet 410 broadcast from the short-range wireless communication device 300 is designated as ADV_NONCONN_IND, the neighboring mobile terminal device 100 receives the location identification information And may not transmit or receive another signal to / from the short range wireless communication apparatus 300.

Meanwhile, when the user's mobile terminal apparatus 100 operates in a scanning state or a starting state and is located within a certain distance from the near field wireless communication apparatus 300 in the proximity of the user, And obtain location identification information included in the AdvData field 434. [0050]

The SCAN_REQ, SCAN_RSP, and CONNECT_REQ will be described in detail with reference to FIG. 15 and FIG.

12 is a diagram illustrating a short-range wireless communication method of an advertiser and a scanner according to an embodiment of the present invention. Referring to FIG. 12, an advertiser can broadcast an advertisement channel packet ADV_INV using up to three advertisement channels (channels 37 to 39). In this case, the scanner can receive the advertisement channel packet ADV_INV sent from the advertiser and send the scan request to the advertiser as the advertisement channel packet SCAN_REQ to request more information. Here, the PAYLOAD of the SCAN_REQ PDU may include a ScanA field including a public or random address of the scanner, and an AdvA field including an advertiser's public or random address.

Meanwhile, the advertiser receiving the scan request can transmit the scan response corresponding to the scan request to the scanner, which has requested the scan with the advertisement channel packet (SCAN_RSP). Here, the PAYLOAD of the SCAN_RSP PDU may include an AdvA field including an advertiser's public or random address, and a ScanRspData field including data at the advertiser's host.

Accordingly, the scanner requested to be scanned can receive more information generated by the advertiser through the advertisement channel.

13 is a diagram illustrating a short-distance wireless communication method between an advertiser and an initiator according to an embodiment of the present invention. Referring to FIG. 13, an advertiser may broadcast an advertisement channel packet ADV_INV using up to three advertisement channels (channels 37 to 39).
